Schneider Electric LC1D09 Low Voltage AC Contactor

Schneider Electric LC1D09 TeSys Deca 3-pole AC contactor is a compact motor-control device designed for AC-3 loads, featuring three normally open contacts and nonreversing operation for straightforward on/off control of small motors. It is rated for about 9 A, with AC-3 control up to 440 V in standard configurations (and some variants listed at 480 V for particular applications, delivering around 5 HP at 480 VAC). Coil voltage varies by variant: several LC1D09 configurations use a low‑consumption 24 V DC coil (for example LC1D09BL/ABL), while other codes offer 100–250 V AC/DC coils (as seen in AKUE variants), allowing compatibility with different control circuits. The family emphasizes easy wiring with snap‑in terminals and a robust short‑circuit current rating (SCCR) up to 100 kA, suitable for panel installations where fault protection is a concern. Some variants include built‑in auxiliary contacts (for example 1 NO, 1 NC in LC1D09ABL), providing additional signaling or interlocking without requiring immediate external modules. This Contactor is widely used for motor-start/stop in applications such as pumps, fans, conveyors, and other moderate‑power loads, where a reliable, code‑compliant AC switch is needed to control a motor or similar inductive load.
